Proton image and momentum distributions from light-front dynamics

We apply a dynamical three-constituent quark light-front model to study the proton. The dynamics is based on notion of diquark (bound or virtual) as dominant interaction channel, which paramaterizes contact between quarks in order build three-body Faddeev Bethe-Salpeter equations for valence state, and we focus totally symmetric part wave function. Dirac electromagnetic form factor used fix parameters, function obtained. From that investigate its Ioffe-time image, non-polarized longitudinal transverse momentum distributions, double distribution.
